I tried the manual "learn" mode and also used the 700 as the "instructor" for the 850 and no luck!
The 850 learns the ON/OFF correctly, and the 850 is putting out an IR beam (I have an IR detector) even with the buttons that the Sub will not respond too. I suspect the code is getting corrupted. The 700 will learn everything correctly from the Velodyne remote.
I used several other remotes that I tried on the 850 and they are all "recorded" correctly.

Is there any additional learning capabilities of the 850 over the 700 that may be creating an issue??

I will give the URC a call tomorrow as it appears they don't respond to Emails.
